Re: Certification for Schrader Transmitter Model(s): G403MA4 FCC ID: MRXG403MA4 IC: 2546A-G403MA4 REQUEST FOR CONFIDENTIALITY Pursuant to 47 CRF 0.459, Schrader requests that a part of the subject application be held confidential. This comprises Exhibits (5) Schematics (9) Internal Photos (DUT is potted) (10) Parts List (Part of Exhibit only) Schrader has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 March 25, 2007 RE: Schrader Electronics Limited FCC: MRXG403MA4 After a review of the submitted information, I have a few comments on the above referenced Application. Depending on your responses, kindly understand there may be additional comments. 1) Most of the emissions must meet with 15.231(e) timing. However plot 6.1(a) – top plot does not adequately show that all 8 word transmissions occur < 1 sec. In fact it appears that the time is just over 1 second in the plot provided. Note that you can not simply mix 15.231(e) and 15.231(a) (i.e. show that 8 words meets 5 second transmission time). 2) Regarding the 40 word transmission for Learn Mode, please provide information to explain or show that this transmission is < 10 seconds as required by 15.231(a)(5) and 5 seconds as required by RSS-210 A1.1.5. Note that IC does not currently have a 10 second requirement in their standard similar to 15.231(a)(5). Timothy R.

Per FCC correspondence, service modes fall under FCC part 15.231(a)(5). Response to Inquiry to FCC (Tracking Number 378112) Joseph Brunett <[email protected]> Generic Office of Engineering Technology <[email protected]> Thu, Jun 22, 2006 at 11:48 AM To: [email protected] Inquiry: Tire Pressure Monitor Transmitters (15.231 devices) contain special modulation modes that are used to setup and program the tire pressure monitoring system on the vehicle. They are used in factory and service environments (i.e. vehicle/tire dealers) only. Since these procedures require special equipment and training, they will not be evoked by the consumer. Would operation in these modes fall under FCC section 15.231 (a) (5), or under FCC Part 2.803(d),2.803(e)(1)(iv),(v), and 2.803(e)(2), or both? Sincerely, JDB Response: The special modulation modes, used for setup of the tire gauge device, will fall under Section 15.231(a)(5) only in this case. Do not reply to this message.

Liepa Report approved by: _____________________ Valdis V. Liepa Test Report Prepared by: Joseph D. Brunett Research Scientist Summary Tests for compliance with FCC Regulations Part 15, Subpart C, and Industry Canada RSS-210/GEN, were performed on Schrader Electronics Limited model(s) G403MA4. This device is subject to the Rules and Regulations as a Transmitter. In testing completed on March 20, 2007, the device tested in the worst case met the allowed FCC specifications for radiated emissions by 4.4 dB (see p. 6). Besides harmonics, there were no other significant spurious emissions found; emissions from digital circuitry were negligible. The conducted emission tests do not apply since the device is powered from a 3 VDC battery.
